//! Re-export of [`diesel`] with prelude types overridden with `async` variants
//! from [`diesel_async`].
//!
//! # Usage
//!
//! To use `async` `diesel` support provided here, enable the following
//! dependencies in your `Cargo.toml`:
//!
//! ```toml
//! [dependencies]
//! rocket = "=0.5.0-rc.3"
//! diesel = "2"
//!
//! [dependencies.rocket_db_pools]
//! version = "=0.1.0-rc.3"
//! features = ["diesel_mysql"]
//! ```
//!
//! Then, import `rocket_db_pools::diesel::prelude::*` as well as the
//! appropriate pool type and, optionally, [`QueryResult`]. To use macros or
//! `diesel` functions, use `diesel::` directly. That is, _do not_ import
//! `rocket_db_pools::diesel`. Doing so will, by design, cause import errors.
//!
//! # Example
//!
//! ```rust
//! # #[macro_use] extern crate rocket;
//! # #[cfg(feature = "diesel_mysql")] {
//! use rocket_db_pools::{Database, Connection};
//! use rocket_db_pools::diesel::{QueryResult, MysqlPool, prelude::*};
//!
//! #[derive(Database)]
//! #[database("diesel_mysql")]
//! struct Db(MysqlPool);
//!
//! #[derive(Queryable, Insertable)]
//! #[diesel(table_name = posts)]
//! struct Post {
//! id: i64,
//! title: String,
//! published: bool,
//! }
//!
//! diesel::table! {
//! posts (id) {
//! id -> BigInt,
//! title -> Text,
//! published -> Bool,
//! }
//! }
//!
//! #[get("/")]
//! async fn list(mut db: Connection<Db>) -> QueryResult<String> {
//! let post_ids: Vec<i64> = posts::table
//! .select(posts::id)
//! .load(&mut db)
//! .await?;
//!
//! Ok(format!("{post_ids:?}"))
//! }
//! # }
//! ```
